Recognition of a rare intrathoracic rib with computed tomography: a case report

Abstract

One of the uncommon congenital variations is intrathoracic rib which a normal, a bifid, or an accessory rib lies within the thoracic cavity that is founded accidentally. Clinically, in most cases they are without symptoms; however, it may cause intrathoracic problems therefore it is important for radiologists and physicians to identify to prevent of excessive intervention and treatment during imaging diagnostic techniques of thoracic problems. In this report, we provide the case of a rare presentation of an intrathoracic rib in a 3-year-old boy arising from the inferior portion of a second rib based on findings from computed tomography. To our knowledge, this is only the second reported case of this type of intrathoracic rib that demonstrated with computed tomography.

Single-port thoracoscopic intrathoracic rib resection: a case description

“…At present, there are over 60 reports of intrathoracic ribs, and 85% of intrathoracic ribs are found by accident (1). A diagnosis of intrathoracic rib is mainly based on a chest X-ray, but chest CT and 3D rib reconstruction have increased the simplicity and accuracy of its diagnosis (9). As an intrathoracic rib itself is a benign disease, researchers have mainly sought to differentiate it from some other diseases, such as lung consolidation, pleural lesions, peripheral lung parenchymal lesions, bony lesions, and subpleural malignant diseases (9).…”

Costilla intratorácica. A propósito de un caso y revisión de la literatura

“…1,2 Fueron reportadas por primera vez en 1940 en Alemania por Lutz, y se han descrito pocos casos en la literatura hasta la actualidad. 4,5,6 En la literatura peruana, no se ha reportado ningún caso publicado. Figura 2.La reconstrucción volumétrica con recomposición 3D muestra una costilla supernumeraria de tipo 1A, que se extiende hacia la región lateral y caudal de la caja torácica.…”

“…4 Pueden ser diagnosticados a través de una radiografía simple de tórax, pero el mejor método diagnóstico para evaluar el origen de las costillas intratorácicas es la tomografía computarizada y así evitar confundirlas con otro proceso patológico. 6,7…”

Supernumerary lumbar ribs: a rare occurrence on an adult African male skeleton

“…A review of literature reveals a global incidence of cervical ribs ranging from 0.04% up to 4.5% [4], intrathoracic ribs in about 50 cases to date [5] and very few reports on supernumerary ribs in the lumbar [367] and sacral regions [1] so rare that no consensus has been established on their incidence or prevalence rates. The presence of lumbar ribs may cause errors in enumerating the vertebral segments or levels on radiographs [2].…”

“…Lumbar ribs are persistent costal elements of the vertebrae that have failed to undergo the normal fusion and apoptotic changes consistent with costal elements in all normal non-thoracic vertebrae [ 1 2 3 ]. A review of literature reveals a global incidence of cervical ribs ranging from 0.04% up to 4.5% [ 4 ], intrathoracic ribs in about 50 cases to date [ 5 ] and very few reports on supernumerary ribs in the lumbar [ 3 6 7 ] and sacral regions [ 1 ] so rare that no consensus has been established on their incidence or prevalence rates. The presence of lumbar ribs may cause errors in enumerating the vertebral segments or levels on radiographs [ 2 ].…”
